GEORGE A. GOODSON, OF MINNEAPOLIS, MINNESOTA, ASSIGNOR TO TI-IE MINNEAPOLIS ELECTRO-MATRIX COMPANY, OF SAME PLACE.

ATTACHMENT FOR TYPE-WRITING MACHINES.

SPECIFICATION forming part of Letters Patent No. 427,680, dated May 13, 18910. Application filed April 24, 1888. l Serial No. 271,691. (No model.)

To @ZZ whom it may concern.-

Be it knovvn that I, GEORGE A. GOODSON, a citizen of Canada, residing at Minneapolis, county of Hennepin, State of Minnesota, have invented certain new and useful Improvements in Attachments for TypeTVriting Machines, of which the following is a specication, reference being had to the accompanying drawings.

My invention is designed more particularly for use in connection with matrix-making machin es. It has for its obj ect to prepare a copy in such a manner that the lines Will justify on the matrix-1nachine A common unit is adopted to measure the characters and the printed column. This unit is small enough to meas ure the smallest character ever used. Every other character is a multiple of this unit. The characters are then classified into groups according to the space required by each. A differential feed is provided, adapted to move the matrix material variable lengths, according to the particular character to be impressed. For the purpose of making the impressions on the matrix material and the stereotype-plate taken therefrom, and consequently the printed matter, come out even at the end of the line, or to have such matter properly justified, it is necessary to provide some system for distributing' odd spaces between the Words and to measure the copy by the common scale in order to see how many of such spaces it will be necessary to distrib'- ute. To this end I run all the copies through a type-writer having like characters to those used onthe matrixanachine.

A measuring device is connected to the typewriter, Which constantly indicates to the eye of the operator the number of units of space still remaining` in the line. As he approaches the end of the line, if the Word or syllable next in order requires such a number of units that it Will not come out even, or to justify t-he line, he strikes a number at the end of the line'denoting the number of units of space left over and carries forward the Word or syllable to the beginning of the next line. The right-hand margin of the copy thus prepared Will contain numerals at the ends of the incomplete lines indicating the number of units of space tobe distributed back between the Words to make the lines justify on the matrix-machine.

In order to be sure that the copy shall be measured by exactly the same scale as the matrix-machine, a registering mechanism is used in connection With the type-Writer, which is identical in character, so far as the space movements are concerned, with the mechanism used to feed the matrix material along` the line in the matrixanachine. I use electrically-controlled escapement-stops for variably limiting the movement of a pointer-shaft under tension.

In the drawings, like gures referring to like parts throughout, Figure l is aplan View of my machine. Fig. 2 is a longitudinal sectional view of the recording mechanism. Fig. 3 is a side elevation of a part of an ordinary caligraph. Figs. 4 and 5 are sectional views of modified constructions. Fig. G is a view of the dial of Fig. 5 in plan. Fig. '7 view of an escapement-Wheel provided with graduations and a stationary pointer.

A suitable frame isformed by a pair of metallic plates A A, which are connected to- `gether and held at a proper distance apart by shouldered posts u, located at their opposite corners.

Referring to Figs. l and 2, B is a dial supported by posts I), attached to the top plate A. This dial is graduated by the common scale, having' the same number of divisions as the printed line has units of space. For eX- ample, if theline contains one hundred units the dial will be graduated into one hundred divisions, numbered from 100 to l,consecu tively.

B is a pointeidriving shaft journaled in the plates A A. Its upper end is extended, passing through a central hole in the dia-l, and is provided With a pointer B.

C is a motor-spring attached at one end to a fixed support on the post c and at the other to the shaft B', and when Wound up tends to move said shaft and pointer in a constant direction.

D is a pinion iixed to the shaft B.

E is a vertical shaft journaled in the plates A A, and having its upper end extended above the latter.

E is a pinion on the shaft E.

IOO

F is a shaft journaled in the plates A A between B and E, and is provided with a pinion F', engaging with the pinion D, and also with a pinion F engaging with the pinion E. To the top of the shaft E is secured a ratchet-wheel G.

H is an armature-lever, pivoted at H and provided at its free end `with arms 72. h', extending to the vicinity of the periphery of the ratchet-wh eel. The arm 71. extends slightly beyond the periphery of the wheel, and the arm h stops slightly short of the same. To the under side of the extremity ofthe arm 7L is attached a pawl f, adapted to engage with the teeth of the wheel G. The outer end of the arm 7L is provided with a slot g.

Kis a magnet for actuating the armaturelever H.

e is a retraction-spring attached at one end to the armature-lever and at the other to a iixed resistance, as the post e.

L is a stop-lever pivoted at its inner end to the armature-lever 1I and extending beyond the periphery of the ratchet-wheel. It is provided with a projecting lug Z, working in the slot c. The outer portion of this lever is curved outward and backward, and is provided on its inner face with a series of shoulders or step-like offsets d. A retractionspring e is attached to the free end of this stop-lever and to the post e. The stop-lever L is provided on its under side with a fixed pawl Z', adapted to be engaged by the teeth of the ratchet-Wheel.

In a suitable supporting-bar, as M, fixed to the top plate of the machine are mounted in line a series of five movable stops n n2 n3 n4 n and one fixed stop nf', corresponding to the number of groups of characters, the xed stop being located at the outer limit of the series.

N N2 N3 N4 N5 are a corresponding series of armature-levers, pivoted intermediate their extremities to a corresponding` series of posts m m2, dac., and having one end attached each to its respective movable stop.

P P2, P3, P4, and P5 are corresponding series of magnets for operating said armatures.

Q represents the frame of an ordinary caligraph or type-writer.

R represents its bank of keys, corresponding, as before stated, to the character used in the matrix-machine. Six keys o" r2, the., are shown, representing one each of the six groups of characters and spaces. Each key-lever is either composed of metal or is provided with a contact-strip on its underside. From these keys or cont-acts five wires S S2 S3 S"1 S extend one each to the corresponding magnets lP P2, &c., and a sixth wire SG to the magnet K. While but six levers are shown in the drawings, it will be understood that each representsagroup, and that all others of said levers for characters requiring a like printingspace are connected with the appropriate wire. These key-levers are each insulated from the others at the forward end of the type-Writer. A

T is the pivoted lever for releasing the spring-actuated feed-carriage. (Not shown.) The front cross-bar t of this lever lies directly under the key-levers, and is either composed of metal or provided with contact-strips on its top and bottom surfaces connected together.

T is a wooden cross-bar fixed to the frame Q. Attached to T at one end is a spring contact-strip t', having its free end directly under the cross-bar t. From T a wire S eX- tends to a source of electricity.

The return-wires from the magnets P P2, dac., (marked, respectively, p p? p3 p4 195,) all pass to the magnet K, whence a common return-wire W extends to the common source. The contact-strip t and the magnet K are therefore on a common electrical circuit having five branches, one each from each group of characters,through its corresponding stopactuating magnet. This circuit is normally open at the key-board, the contacts t and t being apart.

The operation is as follows: Whenever a particular key is depressed, it is brought into contact with the cross-bar t of the lever T, and on this lever being depressed by the further movement of the key the contacts 151i are brought together and the circuitis closed through the magnet K, and if the character belong to any other than the six-unit group one of the branches is also closed through the corresponding stop-actuating magnet. This circuit may be described as follows: starting from the wire S along the same to strip t, thence to bar t along back to the key-lever depressed and in contact therewith, and thence to its appropriate branch wire S S2 Sg S4 S5 SG and its connections to return-wire W. The effect of this is to throw up the corresponding movable stop and draw the armature II to the magnet K, unlocking the ratchetwheel from thel pawl f and throwing it into engagement with the pawl Z. The wheel G, being under tension from the motor-spring, will turn and carry with it the stop-lever L until one of its shouldersj colnes in contact with the projecting stop. Through thetrain of gear E F F D the pointer B is moved a corresponding distance over the graduated dial. W hen the contact is broken at the keyboard by the separation of t t, which occurs the instant the finger is removed from the key, the springs c and c draw the armaturelever H and the stop-lever L back to their normal positions. ln case a six-unit character-key is depressed, the circuit is closed through K only and the stop-lever L moves to its limit against the dummy or fixed stop n. The stop-lever L is therefore allowed to move a variable distance, which corresponds exactly to the space required by the particular character. The dial records the move- IIO of a spring for actuating mechanism, it is obvious that instead of the motor-spring a weight might be employed.

In Fig. 4: I have shown the gearing intermediate shafts E and B dispensed with, the

' spring connected directly with shaft E, and

the dial B placed at one side of the frame and secured to the plate A with the pointer B upon shaft E.

In Figs. 5 and the dial-plate B is placed upon the shaft E and a stationary pointer B3 employed. In these figures the plates A A are preferably placed in a vertical position or in such position that the dial can be easily seen.

In Fig. 7 I have shown the escapementwheel provided with graduations, and a fixed pointer B3 is made to overhang' it and indicate the amount of movement.

In Figs. a, 5, G, and 7 the escapement-wheel is given a number of teeth corresponding with the number of spaces shown on the dial B in the other figures of the drawings.

What I claim, and desire to secure by Letters Patent, is#

l. The combination, with a type-writer, of a registering device having a variable feed according to the space required for the different characters in properly-spaced printing, and aseparatc connection for each group of characters between the type-writer and thea registering device, each group comprising all characters of the same size, substantially as described.
